Table 1 A description of features selected for the models
Feature | Description |
|---|---|
Age | The patients’ age was registered from their medical records. |
Initial VA grade | We used a standard tumbling E-chart to measure the initial visual acuity. The reproducibility of VA assessment with standard charts was investigated previously [21]. |
Type of trauma and zone of injury | the mechanism of trauma determines the type of trauma that was assessed by history taking. In this study, the zone of injury was determined after careful evaluation of the sclera and cornea in the operating room and determining the extent and distance of the tear to the limbus in OGI patients. |
Relative Afferent Pupillary Defect (RAPD) | To evaluate RAPD in OGI patients, this examination was performed with a standard method in a dark room with the help of a penlight with medium light. The result of Marcus Gunn’s pupil evaluation is recorded in the center’s emergency room after the approval of two ophthalmologists. |
Retinal Detachment (RD) | The diagnosis of RD in this study was made with the help of clinical evaluation and ultrasound. |
Traumatic cataract | Traumatic cataract is the crystallin lens opacification that occurs after a blunt or sharp ocular trauma. |
Endophthalmitis | The diagnosis of post-traumatic endophthalmitis was made clinically in this study. The presence of an anterior chamber inflammation (hypopyon or fibrin reaction), vitritis, and retinitis were the main clinical indicators of post-traumatic infectious endophthalmitis. |
Traumatic optic Neuropathy (TON) | Traumatic optic neuropathy occurs due to direct or indirect damage to the optic nerve caused by trauma to the eye or head. Clinical diagnosis is based on examination findings and history. Performing orbital CT, visual acuity measurement, visual field examination, and optic nerve head and peripapillary optical coherence tomography (OCT) imaging are methods that help to diagnose TON. In this center, the diagnosis of TON is made with the help of the mentioned methods and after confirmation by a neuro-ophthalmologist. |
Intraocular Foreign Body (IOFB) | Clinical examination, ultrasonography, and computed tomography (CT-scan) were used to assess the patients suspected of having IOFB. |
